I think you misunderstood my question.

Suppose:

    s = "a string\n"

I want:

    s == "a string"

OTOH, when I write filters, yours is the exact idiom I use.

This breaks on strings like:

Start:      " string bookended by whitespace \n"
Target:     " string bookended by whitespace "

w/ .rstrip: " string bookended by whitespace"
w/ .strip:  "string bookended by whitespace"

Often the (l|r)?strip methods work fine, but sometimes I need to
preserve " " and "\t" in the string.

Thanks for you help, tho.  =)
